RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application Ser.No. 62/424,211, filed Nov. 18, 2016, entitled ANGULARLY ADJUSTABLE TOOLCONNECTION HAVING THREADED CONNECTOR AND CLAMP-TYPE CONNECTOR, which ishereby incorporated in its entirety by reference herein.

BACKGROUND 1. Field

The present invention relates generally to manually operated tools withhandles. More specifically, embodiments of the present invention concerna tool holder for interchangeable use with a variety of tools.

2. Discussion of Prior Art

Extension poles have long been used to support various types of manuallyoperated tools, such as paint brushes, for applications where anextended reach is needed. Known extension poles include fixed-lengthpoles and adjustable-length poles (such as telescopic extension poles).Conventional extension poles typically include a distal connectorlocated at the distal end of the pole for removable attachment to thedesired tool (such as a paint brush). Connectors used with prior artextension poles include threaded connectors and frictional connectors.

Prior art extension poles and extension pole accessories have variousdeficiencies. For instance, the threaded connector or frictionalconnector of a conventional extension pole is not readily connectable tothe wide range of available manual tools. Known extension pole adaptorsare available to change the type of connector associated with anextension pole. However, extension pole adaptors are difficult to useand provide an unreliable connection. The size of such adaptors alsomakes them easy to misplace or lose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Turning initially to FIGS. 1, 2, 12, and 13, an adjustable tool holder50 is operable to be releasably attached to various tools. Morepreferably, the tool holder is configured for interchangeable use with avariety of tools provided with different connection elements. The toolholder 50 preferably includes a tool support 52 and a proximal body 53.As will be described, the proximal body 53 preferably includes atelescopic extension pole 54 and a proximal housing 56.

Brushes

Turning to FIGS. 1, 2, and 5-7, the illustrated embodiment shows thetool holder 50 in alternating use with a bristle brush 58 and a rollerbrush 60. The bristle brush 58 (see FIGS. 5-7) is conventional andincludes a bristle head 58 a mounted on a grip handle 58 b that can begrasped by a user. Similarly the roller brush 60 (see FIGS. 1 and 2)includes a cylindrical brush head 60 a rotatably supported by aconnector handle 60 b that can either be grasped by a user or attachedto a threaded connector.

The grip handle 58 b of the brush 58 preferably presents a grip surface58 c, which provides a connection element configured for one manner ofconnection with the tool holder 50. The manner of connection provided bythe grip surface 58 c preferably comprises releasable frictionalinterconnection between the tool support 52 and the grip handle 58 b, aswill be discussed.

Although the grip surface 58 c provides a male connection element to befrictionally engaged by the tool support 52, the grip handle couldpresent an alternative surface for frictional connection (e.g., wherethe handle presents a socket that provides a female connection elementfor frictional engagement with a tool holder).

Furthermore, the principles of the present invention are applicablewhere an alternative bristle brush uses the same working element (i.e.,the bristle head) while utilizing another type of connection elementassociated with a different manner of connection. For instance, thehandle of the bristle brush could be alternatively configured to includea threaded connection element.

The connector handle 60 b of the roller brush 60 preferably presents agrip surface 60 c and includes a threaded female connector 60 d (seeFIG. 1). The threaded female connector 60 d provides a connectionelement configured for another manner of connection with the tool holder50. The manner of connection provided by the connector 60 d preferablycomprises threadably interconnecting the tool support 52 and thethreaded female connector 60 d, as will be explained below.

Although the connector 60 d provides a female connection element to bethreadably engaged by the tool support 52, the connector could presentan alternative connector for threaded connection (e.g., where the handleof the roller brush presents a threaded shaft that provides a maleconnection element for threaded engagement with a tool holder).

It is also within the ambit of the present invention where analternative roller brush uses the same working element (i.e., the rollerhead) while utilizing another type of connection element associated witha different manner of connection. For instance, the brush could use thegrip surface of the handle as a connection element for frictionalinterconnection between the tool support and the handle.

The principles of the present invention are also applicable where thetool holder 50 receives and engages alternative tools. For instance, thetool holder could be alternatively configured to engage various othermanually held tools, such as other painting tools (e.g., a foam brush,paint edger, corner painter, etc.), a letter-changing tool for anadvertising sign, a cleaning tool (e.g., a dusting tool or a scrapingtool), a washing tool (e.g., a water spray nozzle), surface finishingtools (e.g., sanding tools or staining tools), etc. Such alternativetools could include connection elements similar to those found on thedepicted brushes or another type of connection element.

Proximal Body with Extension Pole

Turning to FIGS. 3, 4, and 9-11, the extension pole 54 preferablycomprises a telescopic pole with inner and outer pole sections 62,64that are telescopically interfitted and slide relative to one anotheralong a pole axis P (see FIG. 1). The pole 54 also presents proximal anddistal pole ends 66 a,b (see FIG. 1). The extension pole 54 furtherincludes a cam mechanism 68 (see FIGS. 5-11) to selectively lock thepole sections 62,64 in a predetermined position relative to one another.

The inner pole section 62 preferably presents oppositely spacedlongitudinal planar sides 70 (see FIGS. 5-11). As will be discussed, thesides 70 are configured to engage the housing 56 and restrict relativerotation therebetween about the pole axis P. The distal pole end 66 bpresented by the inner pole section 62 is preferably slotted (see FIGS.8, 20, and 24) to permit pivoting of the tool support 52 relative to theproximal housing 56.

Turning to FIGS. 5-11, the cam mechanism 68 includes complementalproximal and distal sleeves 72,74 that are rotatably mounted to oneanother. The distal sleeve 74 presents an inner bearing surface 74 a anda bore 74 b (see FIG. 8). The inner bearing surface 74 a defines anannular groove 74 c. The bore 74 b generally corresponds in shape to theinner pole section 62 (see FIG. 6) and includes opposed flats thatslidably engage the longitudinal planar sides 70 of the inner polesection 62. The distal sleeve 74 also presents opposite lugs 75 at adistal end of the sleeve 74 (see FIG. 8).

The proximal sleeve 72 presents a socket 72 a that preferably receivesand is fixed to a distal end 76 of the outer pole section 64 (see FIG.10). The proximal sleeve 72 also includes a cam sleeve 78 defined by anouter bearing surface 78 a and an offset bore 78 b (see FIGS. 8-11). Theouter bearing surface 78 a presents an annular rib 78 c. The bore 78 bis preferably axially offset from the outer bearing surface 78 a so thatthe thickness of the cam sleeve 78 tapers circumferentially (see FIG.11).

The inner bearing surface 74 a of the distal sleeve 74 is slidablyreceived on the outer bearing surface 78 a of the proximal sleeve 72 sothat the sleeves 72,74 are rotatable relative to one another. The rib 78c slidably engages the groove 74 c to restrict axial separation of thesleeves 72,74.

The proximal sleeve 72 and the outer pole section 64 are fixed to oneanother. Preferably, the proximal sleeve 72 and outer pole section 64are rotatable relative to the distal sleeve 74 and inner pole section 62into and out of a locked condition (see FIGS. 9-11). In the lockedcondition, the sleeves 72,74 are urged into frictional engagement withthe inner pole section 62 to lock the pole sections 62,64 and restrictrelative axial sliding movement therebetween. Similarly, the proximalsleeve 72 and outer pole section 64 are rotatable into an unlockedcondition (not shown). In the unlocked condition, frictional engagementbetween the sleeves 72,74 and the inner pole section 62 is preferablyminimized so that the pole sections 62,64 can freely slide axiallyrelative to one another.

The illustrated pole 54 and the proximal housing 56 cooperativelyprovide the proximal body 53. The proximal body 53 is coupled to thetool support 52 adjacent the distal end 66 b, as will be discussed. Theextension pole 54 provides a preferred embodiment of an elongatedgrasping handle. However, it will be appreciated that the tool holdercould have various handle configurations without departing from thescope of the present invention.

Although the tool holder 50 preferably includes the extension pole 54,it is equally within the scope of the present invention where analternative handle structure is provided to grasp the tool holder. Forinstance, the pole 54 could be replaced with a unitary handle element.It will be appreciated that alternative tool holder embodiments couldinclude handles of various lengths. For some aspects of the presentinvention, the proximal body could alternatively include a connector forattachment to another extension pole (e.g., a handle may be eliminatedentirely).

Turning to FIGS. 12-24, the illustrated proximal housing 56 ispreferably attached to the inner pole section 62 and is adjustablyattached to the tool support 52. The proximal housing 56 preferablyincludes a frame 82, a slidable catch 84, a shiftable lever 86, and aspring 87. The proximal housing 56 also presents a housing axis H (seeFIG. 13).

The illustrated frame 82 includes opposite frame sections 82 a,b thatcooperatively support the catch 84 and the lever 86. The frame sections82 a,b are removably attached to one another and cooperatively define aslotted cavity 88 (see FIGS. 12 and 13) to receive the catch 84, lever86, and spring 87. The frame 82 also includes an axle 90 (see FIGS. 13and 23) that rotatably receives the tool support 52.

Yet further, the frame sections 82 a,b present respective flat surfaces92 (see FIGS. 14 and 15). The flat surfaces 92 are shaped to engagecorresponding sides 70 of the inner pole section 62 and restrictrelative rotation therebetween about the housing axis H.

The frame 82 is removably secured within the inner pole section 62 bythreaded fasteners 94 (see FIGS. 23 and 24). However, it is also withinthe ambit of the present invention where the proximal housing 56 andextension pole 54 are alternatively secured to one another.

In the illustrated embodiment, the housing axis H is substantiallycoaxially aligned with the pole axis P (see FIG. 13), although the axesP,H can be off-axis relative to one another.

Turning to FIGS. 12, 13, 17, 18, 23, and 24, the depicted catch 84 isconfigured to selectively engage the tool support 52 and restrictpivotal movement of the tool support 52 relative to the proximal housing56. The catch 84 is preferably unitary and presents two (2) rows 96 ofteeth at one end thereof to releasably engage the tool support 52 (seeFIG. 24). Each toothed row 96 is curved to form a generally concaveshape that receives a complementally shaped row of teeth. At the otherend of the catch 84, the catch 84 presents a catch bearing surface 98(see FIGS. 17 and 18). The catch 84 is slidably received between theframe sections 82 a,b and is slidable between an engaged position (seeFIGS. 12 and 13) and a disengaged position (see FIGS. 17 and 18).

The lever 86 is configured to be selectively operated by a user and isshiftable to permit proximal and distal sliding of the catch 84. Thelever 86 includes a hinge portion 99 (see FIGS. 12 and 13) pivotallymounted on the frame 82. The lever 86 also presents a lever bearingsurface 100 (see FIG. 24) that slidably engages the catch bearingsurface 98. The spring 87 engages the lever 86 and is configured to urgethe lever 86 into an extended position (see FIGS. 12 and 13) associatedwith the catch 84 in the engaged position. The lever 86 is configured tobe depressed by the user and shifted from the extended position to aretracted position (see FIGS. 17 and 18). With the lever 86 retracted,the catch 84 is operable to be displaced proximally from the engagedposition to the disengaged position.

The frame 82, catch 84, and lever 86 are each preferably formed of asynthetic resin material. Most preferably, the frame 82, catch 84, andlever 86 are injection molded from a synthetic resin. However, theprinciples of the present invention are applicable where one or more ofthe frame, catch, and lever include an alternative material, such as ametal material (e.g., aluminum, carbon steel, stainless steel, etc.).

Tool Support

Turning to FIGS. 2-5 and 17-24, the illustrated tool support 52 isconfigured for interchangeable use with a variety of tools provided withdifferent connection elements. Preferably, the tool support 52 includesa distal support body 106, a threaded connector 108, and a clampconnector 110 (see FIGS. 2 and 3).

As will be described in greater detail, the connectors 108,110 arepreferably shiftable relative to one another so as to be alternativelylocated distally. Each connector 108,110 is at least in partpositionable distally of the other connector 108,110 to facilitateconnection to the connection element of the corresponding tool (such asone of the brushes 58,60). Furthermore, according to some aspects of thepresent invention, each connector 108,110 and the corresponding tool arepreferably configured to provide the sole connection between the toolholder 50 and the corresponding tool.

Referring to FIGS. 17-24, the distal support body 106 is preferablyconfigured to support the tool connectors 108,110 so that the toolconnectors 108,110 are shiftable relative to one another and can bealternatively located distally to facilitate connection to a connectionelement of a respective tool. As will be described, the clamp connector110 can be selectively positioned on the support body 106 for pivotingtherewith.

The depicted support body 106 is pivotally mounted to the proximal body53 and can be selectively secured in various orientations. The supportbody 106 preferably includes a pivot frame 112 and a tube 114 thatreceives a distal end of the pivot frame 112. The support body 106 alsodefines a support axis S (see FIGS. 13 and 20).

The depicted tube 114 is unitary and includes a tubular body 116 thatpresents proximal and distal ends 116 a,b (see FIGS. 21 and 24). Thetube 114 also includes a conically shaped receptacle 118 integrallyformed with the body 116. The receptacle extends partly into the body116 from the distal end 116 b.

The tube 114 also preferably presents oppositely spaced longitudinalplanar sides 120 (see FIG. 23) similar to the sides of the inner polesection 62. At the distal end 116 b, the tube 114 defines an endlesstoothed margin 122 (see FIG. 24) configured to engage the threadedconnector 108. The receptacle 118 also presents a splined bore 124 (seeFIG. 24). The tube 114 further presents opposite lugs 126 at theproximal end 116 a (see FIGS. 23 and 24).

The pivot frame 112 is preferably configured to selectively engage thecatch 84 and restrict pivotal movement of the tool support 52 relativeto the proximal housing 56. The frame 112 preferably presents a bore 128(see FIGS. 12, 17, 23, and 24) that is rotatably received on the axle90. Thus, the frame 112 and proximal housing 56 cooperatively form apivot joint 130 (see FIGS. 13, 18, and 20) that permits the tool support52 to swing relative to the proximal body 53.

Although the pivot joint 130 is preferably formed by the depictedstructure of the support body 106 and the proximal housing 56, the pivotjoint 130 could be alternatively configured (as will be shown insubsequent embodiments).

The pivot frame 112 also preferably presents two (2) rows 132 of teethat one end thereof to releasably engage the catch 84 (see FIGS. 18, 23,and 24). Each toothed row 132 is curved about the bore 128 to form agenerally convex shape. Each toothed row 132 is configured to releasablyengage a corresponding toothed row 96 of the catch 84 when the catch 84is in the engaged position.

Thus, in the engaged position, the pivot frame 112 and proximal housing56 cooperatively restrict relative pivotal movement between the toolsupport 52 and the proximal housing 56 (see FIGS. 12 and 13). In thedisengaged position, the toothed rows 96,132 are preferably disengagedfrom each other to permit relative pivotal movement between the toolsupport 52 and the proximal housing 56 (see FIGS. 17 and 18).

Each pair of engageable toothed rows 96,132 are preferably configured tobe removably engaged with one another in a plurality of discreteorientations of the tool support 52 and proximal housing 56. That is thetoothed rows 96,132 permit the tool support 52 and proximal housing 56to be adjustably engaged in one of a range of discrete pivotalpositions.

While the tool holder 50 preferably includes the depicted structure ofthe pivot frame 112 and proximal body 53 to provide adjustable pivotingof the tool support 52, the tool holder 50 could include alternativestructure (as shown in subsequent embodiments) for adjustable pivotingof the tool support.

The pivot frame 112 is preferably formed of a synthetic resin material.Most preferably, the frame 112 is injection molded from a syntheticresin. However, the principles of the present invention are applicableto forming the frame from an alternative material(s), such as a metalmaterial (e.g., aluminum, carbon steel, stainless steel, etc.), oralternative techniques, such as extrusion, machining, etc.

The pivot joint 130 permits the support body 106 to swing relative tothe proximal body 53 between an aligned condition (see FIGS. 12, 13, 17,and 18) and a maximum offset condition (not shown). In the alignedcondition, the housing axis H and the support axis S are substantiallycoaxially aligned with one another (see FIG. 13). When the pivot joint130 is disengaged, the support body 106 can be swung into and out of thealigned condition.

The pivot joint 130 can be disengaged to swing the support body 106among a range of positions where the housing axis H and the support axisS are off-axis relative to each other and define an offset angle θ(e.g., see FIG. 20). In the maximum offset condition, the axes H,Scooperatively define a maximum value of the angle θ. The maximum angle θpreferably ranges from about eighty degrees (80°) to about one hundredtwenty degrees (120°), although the maximum angle θ could fall outsidethis range in certain aspects of the present invention.

The principles of the present invention are applicable where the distalsupport body is alternatively constructed (e.g., to provide analternative mechanism that permits relative shifting of the connectors108,110). Furthermore, the distal support body could be alternativelyshiftably mounted relative to the proximal body 53.

Yet further, for some aspects of the present invention, the tool holdercould be devoid of a support body. For instance, at least one of theconnectors 108,110 could be alternatively configured for attachment tothe proximal body. In some alternative embodiments, one of theconnectors could also be mounted to the other one of the connectors.

Tool Connectors

Turning to FIGS. 20-24, the threaded connector 108 comprises one type oftool connector. As will be discussed, the threaded connector 108provides one manner of tool connection that involves releasable threadedinterconnection between the threaded connector 108 and the roller brush60 (or another tool).

The threaded connector 108 preferably includes a connector body 134,fasteners 136, and a spring 138. The connector body 134 preferablyincludes a threaded shaft 140 that extends distally from a toothedflange 142. The connector body 134 further includes a splined shaft 144that extends proximally from the flange 142.

The connector body 134 is preferably formed of a synthetic resinmaterial. Most preferably, the connector body 134 is injection moldedfrom a synthetic resin. However, the principles of the present inventionare applicable to forming the connector body from an alternativematerial(s), such as a metal material (e.g., aluminum, carbon steel,stainless steel, etc.), or alternative techniques, such as extrusion,machining, etc.

When the connector 108 is installed on the support body 106, the spring138 preferably urges the threaded connector 108 and support body 106into engagement with one another (e.g., see FIG. 20). In the illustratedembodiment, when the connector 108 and support body 106 are engaged, thesplined shaft 144 engages the splined bore 124 and the teeth of theflange 142 engage the toothed margin 122 to restrict relative rotationbetween the threaded connector 108 and support body 106.

The threaded connector 108 is also preferably configured to bedisengaged from the support body 106. In the depicted embodiment, thespring 138 permits the connector body 134 to be shifted distally fromthe support body 106 and disengaged so that the splined shaft 144 isspaced from the splined bore 124 and the flange 142 is spaced from thetoothed margin 122 (see FIGS. 21 and 22).

When disengaged, the connector body 134 is operable to be rotatedrelative to the support body 106 about the support axis S. Theconfiguration of interengaging teeth and splines permit the connectorbody 134 to be removably engaged with the support body 106 in aplurality of discrete orientations. In other words, the connector body134 and the support body 106 are configured to be adjustably engaged inone of a range of discrete rotational positions.

The construction of the depicted connector 108 permits a tool (such asbrush 60) to be securely attached to the connector body 134 and thenselectively rotated with the connector body 134 about the axis S andrelative to the support body 106. This enables the tool to beselectively secured in one of various orientations relative to theextension pole 54.

To secure the tool onto the tool support 52, the threaded shaft 140 ofthe connector 108 is operable to be removably threadably interconnectedwith the female threaded connector 60 d. Thus, the threaded connector108 and the female connector 60 d provide one manner of connecting atool to the tool support 52.

The connector 108 preferably includes a threaded male connector thatprovides for threadably interconnecting the tool support 52 and thebrush 60. However, the connector 108 could present an alternativeconnector structure for threaded connection. For instance, the connectorcould present a threaded socket that provides a female threadedconnection element for threaded engagement with a male threadedconnector of a tool.

It is also within the ambit of the present invention where the connector108 uses another type of connection element (i.e., not a threadedconnection element) associated with a different manner of connection.For instance, the connector could present a surface as a connectionelement operable for frictional interconnection between the tool supportand the tool. For example, alternative frictional, socket-typeconnections are often used in Europe, where the tool or tool holder havea tapered female socket in which a complemental male connector isforcibly inserted to provide frictional connection.

The scope of the present invention is also applicable where theconnector body 134 is alternatively supported for rotation about theaxis S. Furthermore, the connector 108 could be alternatively mountedfor alternative shifting (e.g., sliding as shown in subsequentembodiments). Yet further, for some aspects of the present invention,the threaded connector could be fixed relative to the proximal body 53.

Turning to FIGS. 2-8, the clamp connector 110 comprises another type oftool connector. As will be discussed, the clamp connector 110 providesanother manner of tool connection that involves releasable frictionalinterconnection between the clamp connector 110 and the brush 58 (oranother tool).

The clamp connector 110 preferably includes a clamp body 146, a snapring 148, a clamp lever 150, and a torsion spring 152 (see FIGS. 2 and6). The illustrated clamp body 146 has a unitary and tubularconstruction and is configured to be slidably received on the supportbody 106 and the proximal body 53. As will be explained below, theslidable mounting of the clamp body 146 enables the clamp connector 110to move between a retracted position on the proximal body 53 and anextended position on the support body 106.

The clamp body 146 comprises a unitary structure that includes a tubularsection 154, a loop section 156, and a boss 158 (see FIG. 6). The clampbody 146 also presents proximal and distal ends 160 a,b and a bore 162that extends axially along a bore axis B between the ends 160 a,b (seeFIGS. 4 and 5). The loop section 156 defines the distal end 160 b andpresents a loop opening 164 (see FIGS. 2 and 5) to receive the brush 58(or another tool). Preferably, the loop section 156 presents oppositepairs of scalloped notches that adjustably receive and engage the brushhead 58 a.

The clamp body 146 is preferably formed of a synthetic resin material.Most preferably, the clamp body 146 is injection molded from a syntheticresin. However, the principles of the present invention are applicableto forming the clamp body from an alternative material(s), such as ametal material (e.g., aluminum, carbon steel, stainless steel, etc.), oralternative techniques, such as extrusion, machining, etc.

The snap ring 148 preferably comprises a flexible and elastic ring. Thesnap ring 148 is mounted at the proximal end 160 a and presents acontinuous rim 166 (see FIG. 4). The rim 166 is configured to engage thelugs 75 of the sleeve 74 in the retracted position to restrict distalsliding movement of the clamp body 146 relative to the proximal body 53(see FIG. 4). The rim 166 is also preferably configured to engage thelugs 126 of the support body 106 in the extended position to restrictproximal sliding movement of the clamp body 146 relative to the supportbody 106 (see FIG. 5).

The clamp lever 150 comprises a U-shaped metal body and is pivotallymounted to the boss 158 with a pin. The lever 150 is operable to swingbetween a closed position (see FIGS. 2 and 3), where the clamp lever 150engages the clamp body 146, and an open position (see FIGS. 5-7), wherethe clamp lever 150 and clamp body 146 form an adjustable opening 168 toreceive the brush 58 (or another tool).

The spring 152 preferably engages and urges the clamp lever 150 towardthe closed position. When the brush 58 is received in the openings164,168, the spring 152 urges the clamp lever 150 into frictionalengagement with the handle of the brush 58. As a result, the lever 150cooperates with the clamp body 146 to frictionally grasp the handle andrestrict removal of the brush 58 from the clamp connector 110.

The clamp connector 110 is preferably slidable between the retractedposition and the extended position when the support body 106 andproximal body 53 are in the aligned condition (see FIGS. 3 and 7).

On the other hand, when the proximal body 53 and support body 106 areoff-axis relative to each other, the clamp connector 110 is restrictedfrom sliding between the extended and retracted positions.

The clamp connector 110 is preferably slidable so that the connectors108,110 are shiftable relative to one another along the bore axis B.Again, the connectors 108,110 are preferably shiftable relative to oneanother so as to be alternatively located distally. Each connector108,110 is at least in part positionable distally of the other connector108,110 to facilitate connection to the connection element of therespective tool.

In the depicted embodiment, the clamp connector 110 is preferablylocated in the extended position for attachment to the brush 58 (seeFIGS. 5-7). When in the extended position, the loop section 156 isspaced distally of the threaded connector 108 and support body 106 sothat the opening 164 is unobstructed. Also when in the extendedposition, the connector 110 is preferably located distally of theconnector 108 and partly covers the connector 108. In this manner, theconnector 110 restricts access to the connector 108.

The brush 58 can be selectively inserted through the openings 164,168and releasably frictionally secured therein. When secured, the loopsection 156 releasably frictionally engages the brush head 58 a and theclamp lever 150 and clamp body 146 cooperatively and releasablyfrictionally engage the handle 58 b.

In the extended position, the clamp connector 110 preferably pivots withthe support body 106. That is, the clamp connector 110 is received onthe support body 106 and located distally of the pivot joint 130 so thatthe clamp connector 110 can swing with the support body 106.

On the other hand, in the retracted position, the proximal body 53extends through the bore 162 and across the opening 164 to restrict anytool from being inserted through the opening 164 (see FIGS. 2 and 3).

In the retracted position, the clamp connector 110 preferably does notpivot with the support body 106. That is, the support body 106 isoperable to pivot relative to the proximal body 53 and the clampconnector 110 when the clamp connector 110 is retracted.

For some aspects of the present invention, the clamp connector 110 couldbe configured for use when in the retracted position. For instance, itwill be appreciated that the clamp lever 150 can be opened (e.g., toreceive a tool) when the clamp connector 110 is retracted.

While the illustrated slidable mounting configuration for the clampconnector 110 is preferred, the clamp connector could be alternativelymounted relative to the support body for proximal and distal slidingmovement.

The clamp connector could also be alternatively mounted for alternativeshifting. Yet further, for some aspects of the present invention, theclamp connector could be fixed relative to the proximal body (e.g.,where the threaded connector is axially shiftable relative to the clampconnector and the proximal body).

The clamp connector 110 preferably presents surfaces that provide aconnection element configured for one manner of connection with the toolholder. The manner of connection provided by the clamp connector 110preferably comprises releasable frictional interconnection between thetool support 52 and the respective tool.

However, the clamp connector 110 could present one or more alternativesurfaces for frictional connection (e.g., where the connector presents ashaft that provides a male connection element for frictional engagementwith the complemental socket of a tool, as described above).

Furthermore, the principles of the present invention are applicablewhere the connector utilizes another type of connection elementassociated with a different manner of connection. For instance, theconnector could be alternatively configured to include a threadedconnection element.

Using the Tool Holder

In use, the tool holder 50 is configured to be used interchangeably witha variety of tools, including the brushes 58,60. Each brush 58,60 isconnectable to the tool holder 50 in a different manner. The tool holder50 is preferably used by releasably connecting a first one of the toolsto a first tool connector of the tool holder 50. For instance, the brush58 can be releasably connected to the clamp connector 110.Alternatively, the brush 60 can be releasably connected to the threadedconnector 108.

The first tool connector is preferably located at least in part distallyof a second one of the tool connectors to facilitate connection of thefirst tool to the first tool connector. Thus, if the first toolconnector is not at least partly located distally of the second toolconnector (e.g., where the first tool connector is proximal relative tothe second tool connector), the tool connectors are preferably shiftablerelative to one another to locate the first tool connector at least inpart distally relative to the second tool connector. As disclosed in thepreferred embodiment, relative shifting between the connectors 108,110preferably involves relative shifting along the axis of the tool holder50 and relative to the proximal body 53.

The user can then selectively disconnect the first tool from the firsttool connector. If the brush 58 is connected to the clamp connector 110,the user can selectively disconnect the brush 58 from the clampconnector 110. Similarly, if the brush 60 is connected to the threadedconnector 108, the user can selectively disconnect the brush 60 from thethreaded connector 108.

After connecting a first tool to a first tool connector of the toolholder 50 (and then disconnecting the first tool from the first toolconnector), a second one of the tools can be releasably connected to asecond tool connector of the tool holder 50. Preferably, beforeconnecting the second tool, the first and second tool connectors of thetool holder 50 are shifted relative to one another so as to locate thesecond tool connector at least in part distally relative to the firsttool connector.

This shifting step is preferably done after disconnecting the first tooland the first tool connector from each other. However, it is within thescope of the present invention where the shifting step is done duringthe step of disconnecting the first tool. Furthermore, for some aspectsof the present invention, the shifting step could be done prior to thestep of disconnecting the first tool (i.e., such that the first toolconnector is proximal relative to the second tool connector prior todisconnecting the first tool).

The second tool is preferably releasably connected to the second toolconnector after shifting the first and second tool connectors relativeto one another to locate the second tool connector distally relative tothe first tool connector. However, it is within the scope of the presentinvention where the step of connecting the second tool is done duringthe shifting step. Furthermore, for some aspects of the presentinvention, the step of connecting the second tool could be done prior tothe shifting step (i.e., such that the second tool is connected whilethe second tool connector is proximal relative to the first toolconnector). Yet further, for some aspects of the present invention, thestep of connecting the second tool could be done during or prior to thestep of disconnecting the first tool (such that both tools are connectedto the corresponding tool connectors at the same time). After connectingthe second tool to the second tool connector, the user can selectivelydisconnect the second tool from the second tool connector.

In one example of using the illustrated embodiment, the roller brush 60can be releasably connected to the threaded connector 108. The threadedconnector 108 is preferably located at least in part distally of theconnector 110 to facilitate connection of the roller brush 60 to thethreaded connector 108. Once the brush 60 is connected to the threadedconnector 108, the user can selectively disconnect the brush 60 from thethreaded connector 108. The user can then releasably connect the brush58 to the clamp connector 110. Preferably, before connecting the brush58 to the clamp connector 110, the clamp connector 110 is shifteddistally relative to the proximal body so that the clamp connector 110is located at least in part distally relative to the threaded connector108.

Alternative Embodiments

Turning to FIGS. 25-45, alternative preferred embodiments of the presentinvention are depicted.

With an initial attention to FIGS. 25-29, an alternative tool holder 200is constructed in accordance with a second embodiment of the presentinvention. For the sake of brevity, the description of the alternativetool holder 200 will focus primarily on the differences of thisalternative embodiment from the first preferred embodiment describedabove.

The tool holder 200 preferably includes an alternative tool support 202and proximal body 203. The proximal body 203 includes a telescopicextension pole 204 and an alternative proximal housing 206.

The proximal housing 206 is preferably attached to the extension poleand is adjustably attached to the tool support 202. The proximal housing206 preferably includes a yoke 208, a slidable catch 210, and a spring212 (see FIGS. 25-27). The yoke 208 has a unitary construction andincludes a pair of yoke arms 214 that pivotally receive the tool support202.

The catch 210 is unitary and includes a pawl 216 (see FIG. 27). Thecatch 210 is slidably received in a slot 218 (see FIG. 26) presented byone of the yoke arms 214. The spring 212 is operably mounted within theslot 218 and engages the catch 210 to urge the catch 210 toward a distalend of the corresponding yoke arm 214.

The tool support 202 is configured for interchangeable use with avariety of tools provided with different connection elements.Preferably, the tool support 202 includes a distal support body 220, athreaded connector 222, and a clamp connector 224.

Turning to FIGS. 25-27, the distal support body 220 is configured tosupport the connectors 222,224 so that the connectors are swingabletogether with the support body 220. The connectors 222,224 are alsopreferably swingable relative to the yoke 208 and the extension pole204. In this manner, the connectors 222,224 can be alternatively locateddistally to facilitate connection to a connection element of arespective tool.

The clamp connector 224 preferably includes a clamp cage 226 fixed tothe support body 220. The clamp connector 224 further includes ashiftable pad 228. The pad 228 is rotatably mounted on a threadedfastener 230. The fastener 230 is threadably supported by the supportbody 220 and is rotatable to move the pad 228 toward and away from theclamp cage 226. The cage 226 and pad 228 cooperatively form an opening232 that is adjustably sized and removably receives a tool, such as thebrush B. The clamp connector 224 is configured to be shifted into andout of removable frictional engagement with the brush B.

Each connector 222,224 and the corresponding tool are preferablyconfigured to provide the sole connection between the tool holder 200and the corresponding tool.

Turning to FIGS. 30-33, an alternative tool holder 300 is constructed inaccordance with a third embodiment of the present invention. Thedescription of the alternative tool holder 300 will focus primarily onthe differences of this alternative embodiment from the second preferredembodiment described above.

The tool holder 300 preferably includes an alternative tool support 302and proximal body 303. The proximal body 303 includes a telescopicextension pole 304 and a proximal housing 306.

The proximal housing 306 is preferably attached to the extension poleand is adjustably attached to the tool support 302. The proximal housing306 preferably includes a yoke 308, a pin 310, and a lever 312. The yoke308 has a unitary construction and includes opposite yoke arms 314 thatpivotally receive the tool support 302.

The tool support 302 is configured for interchangeable use with avariety of tools provided with different connection elements.Preferably, the tool support 302 includes a distal support body 316, athreaded connector 318, and an alternative clamp connector 320.

The pin 310 extends through the support body 316 and the yoke arms 314so that the support body 316 is pivotally mounted to the yoke 308. Thelever 312 is attached to one end of the pin 310 and is shiftable into alocking position (see FIGS. 30-33). In the locking position, the pin 310and lever 312 cooperatively shift the yoke arms 314 into frictionalengagement with the support body 316 to restrict rotation of the supportbody 316 relative to the yoke 308. The unsupported end of the lever 312is pivotal away from the yoke 308 (and out of the locking position).With the lever 312 out of the locking position, the pin 310 and lever312 permit the yoke arms 314 to move away from each other and out offrictional engagement with the support body 316. As a result, thesupport body 316 can freely rotate relative to the yoke 308.

The distal support body 316 is configured to support the connectors318,320 so that the connectors 318,320 are swingable together with thesupport body 316. The connectors 318,320 are also preferably swingablerelative to the yoke 308 and the extension pole 304. In this manner, theconnectors 318,320 can be alternatively located distally to facilitateconnection to a connection element of a respective tool.

The clamp connector 320 includes an elongated clamp body with oppositesides 322 (see FIG. 32). The clamp connector 320 also includes anadjustable strap 324 that cooperates with the clamp body to define anopening 326 (see FIG. 32). One end of the strap 324 is pivotallyattached to an unsupported end of one of the sides 322. Another part ofthe strap 324 is adjustably secured to a buckle 328. The buckle 328 isattached to an unsupported end of the other one of the sides 322. Thebuckle 328 is operable to secure the strap 324 in a variety ofpositions. As a result, the strap 324 can be adjusted to change the sizeof the opening 326. By adjustment of the strap 324, the clamp connector320 is configured to be shifted into and out of removable frictionalengagement with the brush B.

The sides 322 of the clamp body are pivotally mounted to the yoke 308 bythe pin 310. In the locking position, the clamp connector 320 isrestricted from pivoting relative to the yoke 308. With the lever 312moved out of the locking position, the clamp connector 32 can freelypivot relative to the yoke 308.

Each connector 318,320 and the corresponding tool are preferablyconfigured to provide the sole connection between the tool holder 300and the corresponding tool.

Turning to FIGS. 34-41, an alternative tool holder 400 is constructed inaccordance with a fourth embodiment of the present invention. Thedescription of the alternative tool holder 400 will focus primarily onthe differences of this alternative embodiment from the first preferredembodiment described above.

The tool holder 400 preferably includes an alternative tool support 402and proximal body 403. The proximal body 403 includes a telescopicextension pole 404 and a proximal housing 406.

The proximal housing 406 is preferably attached to the extension pole404 and is adjustably attached to the tool support 402. The proximalhousing 406 preferably includes a tubular body 408 and a pivotal catch410 (see FIGS. 34 and 35). The body 408 has a unitary construction andpresents a slotted opening 412 that slidably receives the tool support402 and permits the tool support 402 to pivot relative to the body 408(see FIG. 41). The proximal housing 406 further includes a pin 413 fixedwithin the body 408 (see FIG. 37).

The catch 410 is unitary and includes a pawl (not shown) to engagecorresponding slots 414 a,b on the tool support 402 (see FIGS. 36 and37). The catch 410 is pivotally mounted on the body 408. The catch 410is pivotal about a lateral axis into and out of a locking position (seeFIGS. 34, 36, and 41) where the pawl engages one of the slots 414. Theproximal housing also includes a spring (not shown) operably mountedwithin the body 408 to urge the catch 410 into the locking position.

The tool support 402 is configured for interchangeable use with avariety of tools provided with different connection elements.Preferably, the tool support 402 includes a distal support body 416, athreaded connector 418, and a clamp connector 420.

Turning to FIGS. 34-37 and 39, the distal support body 416 is configuredto support the connectors 418,420 so that the connectors are swingabletogether with the support body 416. The connectors 418,420 are alsopreferably swingable relative to the proximal housing 406 and theextension pole 404. Furthermore, the support body 416 permits theconnectors 418,420 to be alternatively located distally to facilitateconnection to a connection element of a respective tool. That is to say,in this embodiment (similar to the first embodiment), the connectors418,420 are also shiftable relative to one another.

The support body 416 preferably includes a slotted proximal section 422and a distal section 424 fixed to one another (see FIGS. 36 and 37). Thesupport body 416 also includes a laterally shiftable keeper 426 mountedin the distal section 424.

The distal section 424 presents a bore 428 that extends axially throughthe distal section 424 (see FIG. 39). The bore 428 is configured toslidably receive the threaded connector 418.

The proximal section 422 comprises a slotted body that presents an axialslot 430 and the slots 414 a,b (see FIGS. 36 and 37). The proximalsection 422 is slidably mounted on the pin 413 and at least partlyslidably received by the body 408 to form a connection joint 434 (seeFIGS. 37 and 41).

The connection joint 434 preferably permits the support body 416 and theproximal housing 406 to slide axially relative to one another between aretracted body condition (see FIGS. 34 and 35) and an extended bodycondition (see FIGS. 36 and 37). In the retracted body condition, thepawl of the catch 410 is urged into engagement with the slot 414 a(corresponding to the locking position) to restrict relative axialsliding movement between the support body 416 and the proximal housing406. The catch 410 can also be shifted out of the locking position sothat the pawl is disengaged and permits relative axial sliding movementbetween the support body 416 and the proximal housing 406 into and outof the retracted body condition.

In the extended body condition, the pawl of the catch 410 is urged intoengagement with one of the slots 414 b (corresponding to the lockingposition) to restrict relative axial sliding movement between thesupport body 416 and the proximal housing 406. The catch 410 can also beshifted out of the locking position so that the pawl is disengaged andpermits relative axial sliding movement between the support body 416 andthe proximal housing 406 into and out of the extended body condition.

Also in the extended body condition, the connection joint 434 alsopreferably permits the support body 416 to pivot about the pin 413 (seeFIG. 41). In the illustrated embodiment, pivoting of the support body416 is substantially restricted to the extended body condition. Inparticular, if the support body 416 is moved proximally out of theextended body condition, the proximal section 422 is slidably receivedin the proximal housing 406 such that the proximal housing 406 andproximal section 422 cooperatively restrict relative pivotal movementtherebetween about the pin 413. The pinned connection of the proximalsection 422 to the proximal housing 406 also restricts relative rotationbetween the support body 416 and the proximal housing 406 about ahousing axis H (see FIG. 36).

Still referring to the extended body condition, the support body 416 isswingable about the pin 413 among a range of positions relative to theproximal housing 406. The slots 414 b, which can each be engaged by thepawl of the catch 410, enable the support body 416 to be secured is aseries of discrete pivotal orientations.

Although the support body 416 preferably includes the axially slottedbody, the tool holder could be alternatively configured so that theproximal body 403 includes an axially slotted body. In such analternative embodiment, the slotted body could be pinned to the supportbody and slidably received in a bore presented by the support body.

Turning to FIGS. 34, 35, and 39, the clamp connector 420 preferablyincludes a unitary collet 436 fixed to the support body 416. The clampconnector 420 also includes a rotatable collar 438. The collet 436includes a pair of opposed jaws 440 and a threaded base 442, with thebore 428 extending through the collet 436 (see FIG. 39). The collet 436is preferably configured to flex so that the jaws 440 are shiftabletoward and away from each other. As discussed below, the collar 438 isoperable to engage and urge the jaws 440 toward each other.

The threaded connector 418 is preferably axially slidable within thebore 428 between a retracted position (see FIG. 40) and an extendedposition (see FIGS. 34 and 35). A spring 443 is also located within thebore 428 and is configured to urge the threaded connector 418 distallytoward the extended position (see FIG. 39). As the threaded connector418 is advanced proximally within the bore 428, the spring 443 applies aprogressively increasing force that urges the threaded connectordistally.

The threaded connector 418 is preferably slidable so that the connectors418,420 are shiftable relative to one another along the axis of the bore428. The connectors 418,420 are preferably shiftable relative to oneanother so as to be alternatively located distally. Each connector418,420 is positionable at least in part distally of the other connector418,420 to facilitate connection to the connection element of therespective tool.

In the illustrated embodiment, the keeper 426 is configured to removablyengage the threaded connector 418 in the retracted position. While thethreaded connector 418 is retracted, the keeper 426 can be depressed bya user to disengage the keeper 426 from the threaded connector 418. Withthe keeper 426 disengaged, the spring 443 urges the threaded connector418 distally out of the retracted position.

The collar 438 comprises a unitary threaded sleeve with an internalthreaded surface 444 (see FIG. 39). The collar 438 also preferablypresents a distal end with a proximally tapering interior surface 446(see FIG. 39).

The collar 438 is threadably received on the threaded base 442. Thecollar 438 is operable to be threaded so that the distal end can bemoved into and out of engagement with tapered side surfaces 448 of thejaws 440 (see FIGS. 34, 35, and 39). As the collar 438 is progressivelydistally advanced in engagement with the jaws 440, the surfaces 446,448slidably engage one another so that the jaws 440 are progressivelyshifted toward one another. In this manner, the jaws 440 can be urgedinto frictional engagement with the threaded connector 418 (see FIG. 39)or the brush B (see FIG. 40).

Turning to FIGS. 42-45, an alternative tool holder 500 is constructed inaccordance with a fifth embodiment of the present invention. Thedescription of the alternative tool holder 500 will focus primarily onthe differences of this alternative embodiment from the fourth preferredembodiment described above.

The tool holder 400 preferably includes an alternative tool support 502and proximal body 503. The proximal body 503 includes a telescopicextension pole 504 and a proximal housing 506.

The proximal housing 506 is preferably attached to the extension pole504 and is adjustably attached to the tool support 502. The proximalhousing 506 preferably includes a tubular body 508 and a pivotal catch510 (see FIGS. 43 and 45). The body 508 has a unitary construction andpresents a slotted opening 512 that slidably receives the tool support502 and permits the tool support 502 to pivot relative to the body 508(see FIG. 44). The proximal housing 506 further includes a pin (notshown) fixed within the body 508. The catch 510 is unitary and includesa pawl (not shown) to engage corresponding slots 514 (see FIG. 45) onthe tool support 502.

The tool support 502 is configured for interchangeable use with avariety of tools provided with different connection elements.Preferably, the tool support 502 includes a distal support body 516, athreaded connector 518, and a clamp connector 520.

The distal support body 516 is configured to support the connectors518,520 so that the connectors are swingable together with the supportbody 516. The connectors 518,520 are also preferably swingable relativeto the proximal housing 506 and the extension pole 504. Furthermore, thesupport body 516 permits the connectors 518,520 to be alternativelylocated distally to facilitate connection to a connection element of arespective tool. That is to say, in this embodiment (similar to thefirst embodiment), the connectors 518,520 are also shiftable relative toone another.

The support body 516 preferably includes a slotted proximal section 522and a distal section 524, with the sections 522,524 being fixed to oneanother (see FIGS. 44 and 45). A bore 528 extends axially through thedistal section 524 (see FIGS. 42 and 43). The bore 528 is configured toslidably receive the threaded connector 518.

The proximal section 522 comprises a slotted body that presents an axialslot 530 (see FIGS. 44 and 45). The proximal section 522 also presentsslots 514 (see FIG. 45). Although most of the slots 514 are notdepicted, the slots 514 are substantially the same in number and inlocation on the proximal section 522 compared to the slots 414 in theprevious embodiment. The proximal section 522 is slidably mounted on thepin and at least partly slidably received by the body 508 to form aconnection joint 534 (see FIGS. 44 and 45) similar to the connectionjoint 434.

The clamp connector 520 preferably includes a unitary collet 536 fixedto the support body 516. The clamp connector 520 also includes ashiftable latch device 538. The collet 536 includes a pair of opposedjaws 540 a,b, with the bore 528 extending through the collet 436 (seeFIG. 42). The collet 536 is preferably configured to flex so that thejaws 540 a,b are shiftable toward and away from each other.

The threaded connector 518 is preferably axially slidable within thebore 528 between a retracted position (see FIGS. 44 and 45) and anextended position (see FIGS. 42 and 43). A spring 542 is also locatedwithin the bore 528 and is configured to urge the threaded connector 518distally toward the extended position.

The threaded connector 518 is preferably slidable so that the connectors518,520 are shiftable relative to one another along the axis of the bore528. The connectors 518,520 are preferably shiftable relative to oneanother so as to be alternatively located distally. Each connector518,520 is positionable at least in part distally of the other connector518,520 to facilitate connection to the connection element of therespective tool.

The latch device 538 preferably includes a lever 544 pivotally mountedto lugs 546, which are fixed to the jaw 540 a. The lever 544 and lugs546 are pivotally attached by a pin 548 that permits rotating movementtherebetween about a lateral axis.

The latch device 538 also preferably includes a unitary wire loop 550swingably attached to the lever 544 at a location spaced from the pin548. The wire loop 550 is operable to be removably engaged with one of aseries of notches 552 presented by the jaw 540 b (see FIG. 42).

The latch device 538 can be moved between a locked condition (see FIGS.42, 44, and 45) and an unlocked condition (see FIG. 43). In the lockedcondition, the latch device 538 urges the jaws 540 a,b toward each otherand into frictional engagement with the threaded connector 518 (see FIG.42) or the brush B (see FIGS. 44 and 45). In the unlocked condition, thelatch device 538 is disengaged from the jaw 540 b so that the collet 536permits the threaded connector 518 or brush B to slide through the bore528.

The latch device 538 can be moved from the unlocked condition to thelocked condition by locating the lever 544 in a distal position (seeFIG. 43). If necessary, the wire loop 550 can be rotated proximally ordistally relative to the collet 536 to position the wire loop 550adjacent one of the notches 552. The lever 544 can then be swungproximally to a proximal position (see FIG. 42) so that the wire loop550 is moved into engagement with the corresponding notch 552.

To unlock the latch device 538, the lever is swung distally to thedistal position so that the wire loop 550 out of the engagement with thecorresponding notch 552. The wire loop 550 can then be swung freelyrelative to the collet 536.

The latch device 538 and collet 536 are preferably configured so thatthe lever 544 is in an over-center condition when the latch device 538is in the locked condition. That is, in the locked condition, the lever544 and wire loop 550 cooperatively restrict distal swinging of thelever 544.
